How To Clean Throttle Position Sensor (TPS)

There are many sensors in your car that monitor your engine to help it run optimally. One of these is the throttle-position sensor. The throttle position sensor helps the ECU monitor how much fuel to inject into your engine. It also ensures that your engine does not stall or over-rev at any point in time. This article will teach you about the throttle position sensor and how to clean it on your Vtec engine. Read on to know more…

What is a throttle position sensor?

A throttle position sensor is an important part of your car’s engine control system. It is fitted to the throttle (the device which controls the flow of air into the engine). The sensor detects the current position of the throttle and sends a signal to the Engine Control Module (ECM). This signal is used in the auto-ignition process and also to regulate the amount of fuel that enters the engine.

How does the TPS work?

The throttle position sensor transmits the position of your throttle to the ECU. The ECU then uses this data from the TPS to regulate the amount of fuel that enters the engine. When you floor the throttle in your car, the sensor sends a high signal to the ECU. This signal tells the ECU to increase the amount of fuel entering the engine (thus giving you more power). When you release the throttle, the sensor sends a low signal to the ECU. This signal tells the ECU to decrease the amount of fuel entering the engine (thus helping you to slow the car down).

When is the TPS cleaned?

The TPS is one of the sensors inside your car that is cleaned during the standard service. If you have your car serviced regularly, then you don’t need to pay any special attention to this sensor. However, if you haven’t had your car serviced in a while and you notice that your Vtec engine has started running poorly, then you should have your TPS checked.

How to clean your throttle position sensor

The TPS is located on the side of your engine on the intake side of the throttle body. You can reach it by removing the intake air duct. You’ll need to remove the duct at the throttle body and the air filter box. After removing the duct, you can get access to the TPS. Now, the TPS is a very small sensor, and so it’s easy to miss if you are cleaning it. A good way to clean the TPS is to remove it and clean it with a paper towel and a bit of rubbing alcohol. After you finish cleaning the sensor, you can reassemble everything and then take your car for another spin to see if the problem is fixed.
